Yup I totally agree, Iraqi Airways was once an excellent airline flying to places like Rio De Janeiro to places like Johanesburg, with planes like the B747 to B727, it would be interresting to see Iraqi Airways!

Airliners.Net has a couple of interesting, extensive search functions. Go here and scroll down to what you're looking for.
You'll see there aren't an awful lot of photos of Iraqi Airways in the database, which is probably why the airline isn't in the pull-down menu, in the first place.

Johan isn't able to respond to queries much at the moment, so I'll answer this one for him ...

There are only 10 photos for Iraqi Airways on the database (I've standardised the airline names for the two that were slightly different so that they are all in one group now), but this simply isn't enough to warrant a separate entry on the Airlines drop-down list. These photos represent only about 0.0001% of the photos on Airliners.net - if we had to assign entries on the drop-down lists to all such "small groups" we would soon end up with very unwieldy lists.

We are, however, very open to hearing suggestions from our users on what they would like to see on these lists. We just added jetBlue Airways the other day, on the recommendation of one of our users.

Interesting. While I would like to think I gave pretty much the same motivation as Andrew did (only - granted - from a non-official point of view), apparently that wasn't as appreciated.
All I did was try and add a way of getting a hold of those photos you were apparently looking for, Redngold.
